“Over the last several years, fact checking has come into its own. Led by organizations like the International Fact-Checking Network, rigorous fact checks are now conducted by more than 100 active sites, according to the Duke University Reporter’s Lab,” announced Google in a statement. “They collectively produce many thousands of fact-checks a year, examining claims around urban legends, politics, health, and the media itself.”

“Google News determines whether an article might contain fact checks in part by looking for the schema.org ClaimReview markup,” the company continued, announcing their own fact-checker. “We also look for sites that follow the commonly accepted criteria for fact checks.”
